I guess I should have looked harder - it appears the map references a theory and not consensus. I just did a google image search and found the first map that included the U.S. and Canada.

Interesting, though, that it occured so soon after the uncontrolled oil seapage in the gulf. Of course, correlation doesn’t imply causality.

If we go another 60 days and have another quake along the line, it might add credence to the theory.

Thanks much for that clarification.
